The features of preparation processes of potassium and barium ferrates(VI) in the presence of a manganese compound contained in the feedstock are studied. It is established that manganese impurities during ferrate synthesis transferred in alkaline solution and in crystalline ferrates in the form of oxoanions MnO42−.
The influence of Mn impurities on the effectiveness of synthesis process of ferrate solutions in various ways is defined. It was revealed that product yield decreases and manganates accumulate in solution during anodic dissolution with increasing manganese content in the anode material.
It is shown that the degree of decomposition of crystalline barium ferrates during in the presence of Mn compounds more than for potassium ferrate derived from the same mother liquor. The degree of decomposition increases with increasing manganese content in solid ferrates.
It is proposed efficiently select the feedstock and include additional purification in inorganic and organic solvents in production cycle to reduce the transition of manganese compounds in the desired product.References
